How about having a lovely cup of tea in a lovely cup? ;)
This was entirely designed using different heart like geometries and in real size.
I've uploaded the .STL of both cup and saucer. So, if you love to have this on your table, you can get it 3D printed by ceramic.
You can print it on Figulo, as long as I've made it according to their design rules.
Hope you will like it :)
